24V G4 SMD LED Disk Internal circuitry provides constant current draw regardless of voltage fluctuations from the source (20 to 32 VDC for 24V models), meaning no flickering and longer LED life.

We got 140 of these from West Marine. 30 or more burnt the rectifier diodes and stunk and quit. At least 7 of them blew the 7 amp fuses. West Marine was good about replacing them. Some that were working okay were left on in a room with the A/C off. They got so hot that they melted the solder and the disk fell off its pins.
We got some 24 volt LED rope lights for under the stairs. I replaced the incandescent strings on 2 stairs. 3 months later, more incandescent strings went bad so I replaced the rest of them. With only occasional use, the LEDs that I had already replaced were a lot dimmer than the new ones from the same spool. So I replaced those 2 strings again and told the captain not to use them unless the owner was onboard.
